When the welding angle needs to be adjusted, the driving motor is controlled to work, thereby driving the worm to rotate, and under the action of the first transmission belt, the other worm is synchronously driven to rotate, so that the arc-shaped toothed rod meshing with it drives the adjusting shaft to deflect on the adjusting frame, and then drives the deflection angle of the metal plate through the receiving plate, so that the two metal plates deflect year-on-year, which is convenient for welding, avoids the need to use other equipment to fix the welding angle of the metal plate, simplifies the working steps, improves production efficiency, and thus improves the practicality of the device.

[0015] In the present invention, a worker places a metal plate horizontally on a workbench and pre-positions the metal plate through the arc-shaped fixed arms on both sides of the workbench, and then controls the electric push rod to work, thereby driving the two metal plates to move in the direction of the welding machine, and according to the welding situation, the welding angle of the metal plate is adjusted by controlling the driving motor to work. In the process of moving, the inclined surface of the first wedge block is abutted against the side end of the adjacent trapezoidal trigger frame through the set trapezoidal trigger plate, thereby driving the two L-shaped connecting rods to move away from each other, thereby driving the sliding block to move in the direction of the trapezoidal trigger frame on the sliding shaft through the movable frame, and then synchronously driving the T-frame and the card shaft to move along the trigger groove, and under the action of the trigger groove, the T-frame slides downward on the movable shaft, and when it is close to the trapezoidal trigger frame, the side end of the T-frame abuts against the top of the trigger plate and drives it to press down, thereby driving the trapezoidal trigger frame to move downward under the action of the telescopic spring rod, and then first driving the trapezoidal trigger The driving frame at the bottom of the frame drives the pushing frame to deflect on the connecting frame toward the trapezoidal trigger frame through the pushing rod, thereby driving the pushing piece to slide in the sliding groove and stretching the damping spring rod, so as to facilitate the two metal blocks on the workbench to be aligned with each other. In the alignment process, the driving rods on both sides of the trapezoidal trigger frame drive the arc-shaped fixed arm to deflect toward the surface of the workbench under the action of the connecting piece and the hinge frame, so that the bottom of the telescopic pressure block is against the surface of the metal plate, and the arc-shaped fixed arm is clamped in the bayonet to complete the fixation of the metal plate after the position adjustment. In this process, the need to manually adjust the position to determine the welding direction of the metal plate by the staff is avoided, and the shaking of the metal plate during welding caused by the unstable hands is further avoided, which affects the welding quality of the metal plate and improves the welding effect. Through the reset spring, after the first wedge block loses its resistance, it can be reset by the reset spring, so as to facilitate the next welding work.

[0016] In the present invention, after the welding of the two metal plates is completed, the electric push rod is controlled to work, thereby driving the two metal plates to move away from the welding machine, and when moving to the position of the ramp plate, the second wedge block is provided, thereby driving the two sliding blocks to move away from the trapezoidal trigger frame on the sliding shaft, and then driving the driving toothed rod to move, and driving the first bevel gear meshing therewith to rotate, so that the second bevel gear and the linkage shaft rotate synchronously, and the rotating shaft is driven to rotate by the second transmission belt provided, so that the two driving wheels rotate synchronously, and then the unloading plate is driven under the action of the auxiliary driving rod to eject the welded metal plate in the direction away from the workbench, and unload it to the side end, completing the unloading work, thereby further improving the practicality of the device.

[0017] In the present invention, by providing a material unloading ramp, when the metal plate is unloaded through the unloading plate, it can be moved along the material unloading ramp to a designated position, thereby improving the convenience during work.

[0018] In the present invention, by providing the silicone soft pad, when the telescopic pressing block contacts the top of the metal plate, the friction between the pressing block and the metal plate can be increased, thereby improving the fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS
